Avionics Mcqs


Q.  Which of the following is not one of the perturbations that make the satellite to vary from its elliptical path?

a. Solar activity
b. Asymmetrical components of Earth’s gravitational field
c. Air drag
d. Motion of a passing comet


ANSWER: See Answer
 
Perturbations cause the orbital plane to oscillate and rotate and vary the satellite from its elliptical orbital path. These forces include spherical asymmetrical components of Earth’s gravitational field, Lunisolar perturbations, air drag, magnetic and static electric forces.
